MARTTC - my AF was a lot shorter post D&C too, I was expecting my 1st one to be very heavy but it wasn't at all.
LilMuffin - Hashimotos runs in my mum's family. She still has some thyroid gland left so her dose needs to keep being checked and varied as sometimes her thyroid works, sometimes it doesn't. Whereas an auntie who has no gland left is just on the highest dose all the time. This would be why your doctor is proceding with caution. You don't want to have too much synthetic thyroid as that comes with its own side effects which can also effect TTC/pregnancy. I expect even on a low dose you will start to see improvements so don't be disheartened, best to get the right dose so your baby can be super-sticky! (the tiredness and depression are both hypothyroid/hashimoto symptoms, so expect them to improve too )
AFM - waiting, waiting, 6 hours til my scan. Will update as soon as I know anything!!
